Abstract

L'invention concerne un procédé de réalisation, dans une paroi externe d'un tube (10), d'au moins un cran (11, 12, 13, 13a, 13b) avec les étapes: ET1 : on guide un premier poinçon (50) comportant une dent de préformage (52) dans la paroi du tube jusqu'à obtenir une protubérance (55, 56), un mandrin (58) cylindrique plein étant positionné à l'intérieur du tube, puis ET2 : on guide un deuxième poinçon (70, 80) avec une dent de poinçonnage (72, 82) dont l'extrémité d'attaque (73, 83) présente une forme complémentaire à une forme du cran à réaliser, dans la paroi du tube, un mandrin de poinçonnage (78) étant positionné à l'intérieur du tube, et présentant une gorge (79) adaptée à contenir la matière refoulée. Application au crantage d'appuie-têtes de siège de véhicule automobile.The invention relates to a method of producing, in an outer wall of a tube (10), at least one notch (11, 12, 13, 13a, 13b) with the steps: ET1: a first punch ( 50) having a preforming tooth (52) in the wall of the tube until a protuberance (55, 56) is obtained, a solid cylindrical mandrel (58) being positioned inside the tube, then ET2: a second guide is guided punch (70, 80) with a punching tooth (72, 82) whose leading end (73, 83) has a shape complementary to a shape of the notch to be produced in the wall of the tube, a punching mandrel (78) being positioned within the tube, and having a groove (79) adapted to contain the repressed material. Application to notching of motor vehicle seat headrests.
